As the Yuba River is a tributary of the Sacramento River, much of that debris then found its way to the San Francisco Bay. In Sacramento, the I Street Bridge had to be raised 20 feet (6.1 m). [6] Lawsuits by farmers curtailed hydraulic mining in 1883, but the slickens remained behind in the river systems. [5]
Merchant ships fill San Francisco Bay, 1850–51. Supply ships arrived in San Francisco with goods to supply the needs of the growing population. When hundreds of ships were abandoned after their crews deserted to go into the goldfields, many ships were converted to warehouses, stores, taverns, hotels, and one into a jail. [32]
Gold was first discovered in this town in 1850. The area under the town was so rich in gold that they moved the town to get to the gold. [3] Marysville was a transportation hub for gold to be shipped out to San Francisco. Millions of dollars in gold came through Marysville, one of the biggest cities in California at the time. [11]

The San Francisco Bay became an outlet for polluting byproducts during the Gold Rush. Hydraulic mining left a trail of toxic waste, called "slickens," that flowed from mine sites in the Sierras through the Sacramento River and into the San Francisco Bay. [6] The slickens would contain harmful metals such as mercury. During this period, the ...
By 1851, quartz mining had become the major industry of Coloma. [24] Once the gold-bearing rocks were brought to surface, the rocks were crushed and the gold separated, either using separation in water, using its density difference from quartz sand, or by washing the sand over copper plates coated with mercury (with which gold forms an amalgam).
New gold mines were found and developed. Nevada gold production continues to expand. Livermore remained active in geology, mineral exploration, and public service. He endowed a chair in Geophysics at the Mackay School of Mines, [7] and supported major programs at Stanford University and the University of Nevada, Reno, usually anonymously. [8]
